Specification of Letters Patent. =Patntgd NQV. 28, 191% Application filed September 21, 1915. Serial No. 51,850.

To all whom it may concern Be it known that 1, CHARLES BREGHT, a citizen of the United States, and a resident of Coatesville, county of Chester, State of Pennsylvania, have invented certain Improvements in Car-Roofs, of which the following is a specification.

One object of my invention is to construct a metal car roof in such a manner that the rivets which retain the roof' sections to the, carline do not extend through the roof.

A further object of .the invention is to provide a vertically .arranged roof sheet support, which is attached to the carline and to which the sheets are also secured.

My invention relates to-certain improvements in the carline which will. be described hereinafter. I

In the accompanying drawings :Figure' 1, is a transverse sectional view on the line a-a, Fig. 2; Fig. "9., is an end view of the carline showing the roof plates in section;

Fig. 3, is a section on the line bb, Fig. 1; Fig. 4, is a plan view of a portion of the car roof, showling the carline in dotted lines: Fig. 5, is a detached side view of one-half of the carline and the roof sheet support secured thereto; Fig. 6, is a plan View of one-half of the carline, showing the roof support attached; and Fig. 7, is a view illustrating a modification of the invention.

Referring to the drawings, 1 is the cornice plate of the car made, in the present instance, as shown in Fig. 1, and to which the side plates 2 are secured by rivets.

4 is a post to which the side plates and the cornice plate are secured.

3 is a brace which extends on the inside of the cornice plate and also on the inside of the side plate of the car.

Each brace 3 is curved at its outer end, as at 6, and has an extension 7 which is attached to the flaring portion 8 of the carline 9 by rivets 10, thus forming an anchor extending from the post or side plate of the car to the carline. The outer end of the carline is cut away and the reduced portion is bent over the upper end of the cornice plate and is secured thereto by rivets 12- The upper end 11 of the cornice plate 1 is bent inward, as at 13, to form a round shoulder around which the carline is Fig. 3, in the form of a channel having side members 14: and at the center of the car. The upper edges of these side members are bent outward, as. at 15, and gradually increase in width toward each side of the car, forming the flaring portions 8 referred to above. At the same time, the carline is reduced in depth from the center toward each edge, as illustrated in Fig. 5, and by this construction I am enabled to secure considerable depth at the center of the'car roof where strength is required and to ,provide a flaring broad surface at each side of the car to'which the braces and the roof plates are rigidly attached, and by designing the carline in this manner it can be made from a plate having parallel sides without material waste.

By making the carline in the form of a channel I provide a duct for the passage of 'water to the sides of the car, should a leak occur at any of the joints of the roof plates.

The base of the carline is pressed up to form a recess 16, as shown in Fig. 3, and the roof sheet support 17 is secured to the base of the carline 9, as clearly shown in said figure. sheet metal having a vertical portion 17 and ahorizontal portion 17". This horizontal portion rests upon the raised portion of the base of the carline and is secured thereto by a line of rivets 18. By forming the recess 16 in the carline, the heads of the rivets are not exposed. The vertical portions 17 of the roof support extend above the upper edge of the carline and the roof plates 19 have vertical flanges 20 at each edge, which are secured to the vertical portion 17 of the roof sheet support by transverse rivets 21 above the roof proper. The roof sheets and the body portion of the roof are notperforated for the reception of the rivets.

I may provide anchor lugs 22 which are welded at 22 to the underside of the roof sheets so that their extensions will project into the carline and thus steady the sheet laterally, taking a portion of the strain off the rivets 21. The roof sheets may be pressed up in any manner desired to form ribs or corrugations, or may be plain without departing from the essential features of the invention.

The joint between the roof sheet support and the flanges of the roof may be callted This roof support is made from v and may, in addition thereto, be protected by a plate 28 which is secured by the rivets 21 and has its upper edge bent over the joint, as illustrated in Fig. 3, or one of the roof sheets may have a flange 20 of greater length than the other, as illustrated in Fig.

7, and bent over the 'joint, producing the same result.

The roof sheet support is reduced in height at each end, as at 17 Fig; 5, and this support is bent over with the portion 11 of the carline, as clearly shown in Figs. 1 and 2. The roof sheets are also bent over the rivets 12 and 12, to separate the roof plates I from the carlines to allow any Water to escape from the channel of the carlines, due to leakage, and to allow for a certain amount of ventilation.

When it is necessary to provide a running board throughout the length of the car, such as indicated at 24, it is attached at intervals to the roof sheet support by angle brackets 25, which are attached to the said support by one or two of the rivets'2l and to the running board by a bolt 26, as clearly shown in Fig. 3, the head of the bolt being located in a recess in the board so that it will not project above the upper surface of the board.

It will be seen by the above construction that I can make a very simple and substantial roof construction in which the carline is made from a plate bent up into form and to which the roof sheet support is attached. The carline has the necessary depth at the center to give it strength and is flared at each end so that it can be readily attached to its anchors or braces to give the structure stability, and the roof sheets are secured to the roof supports by transverse rivets which .lines extending from one cornice plate to the other, channeled in cross section and having flared flanges at each end; roof sheet supports secured to the carlines and extending above the upper edge thereof and also turned down at each end over the cornice plates; and roof sheets' having upturned flanges abutting the roof sheet supports and secured thereto by transverse rivets, said roof sheets also extending down over the cornice plate and the turned over portions of the carlines.

3. The combination of a channeled carline having its base pressed to form a recess; an angular roof sheet support resting on the raised portion of the base of the carline; and rivets securing the two parts together, the lower heads of the rivets resting in the recess, the upper edge of the roof sheet support extending above the carline, the roof sheet having upwardly extending flanges secured to the roof sheet support.

4. The combination in a car roof structure, of cornice plates at each side of the car; a series of carlines U-shaped in cross section extending across the car and having their ends bent down over the edge of the cornice plates; a roof sheet support projecting from the carlines; flanged roof plates, the flanges of which are secured to the said roof sheet support, the edges of the plates being turned down over the cornice plates, the roof sheet being spaced from the carlines at the cornice plates so as toallow for the escape of water from the carlines due to leakage and to allow for ventilation.
